The PAGER details for this are not out yet but there are several million people in the affected area.

The new agencies seem a little confused saying it is off shore when it appears to be on shore.

SANTIAGO, Chile (AP) — A magnitude-7.2 earthquake has struck just off the coast of central Chile, prompting an emergency evacuation order for people living near the ocean in case it spawns a tsunami.

The quake struck 20 miles (32 kilometers) north-northwest of Talca, one of the hardest-hit cities in the huge quake that devastated central Chile two years ago.

There were no immediate reports of deaths or injuries, but the government ordered people living near shore to head for higher ground along a long stretch of the coast.

Bloomberg

Chile’s government emergency office requested the evacuation of coastal areas after a 7.2 magnitude earthquake struck in the Pacific Ocean off Constitucino, a village south of Santiago that was destroyed by a tsunami in 2010.

There is some more immediate info of a technical nature on the Quake Watch thread

This agrees with the GeoAzur tensor solution which also got 7.1 Mw so I think you can say that will be the final value.

Just starting to show on the LISS seismos now.



Still no PAGER data. Not good.

This is the location of the quake.

Shaking intensity moderate so hopefully won't be too bad.



See USGS pages.

Thanks for info Puterman - I have a friend
in that area. Will keep checking back.

The Associated Press is reporting collapse of the telephone system and that the USGS initially reported that the quake occurred offshore. People along the coast were told to evacuate to higher ground.

This is a prelude to the 7.6 that will hit SF on Friday 3/30.
2nd line.

PAGER Data now in. Yellow fatalities and Green economic.

Earth seems to be acting up lately. Just makes you think a big ones coming.....could come tomorrow, or in 600 years.

I presume you mean San Francisco?

I don't see a connection between the two, but time no doubt will tell.

a big one happened last year. and in 2004.

thats 2 big ones.

reply to post by yourmaker


Yes, I guess you are correct.

reply to post by AaronWilson


We are three months into the year and have had 4 mag 7 quakes. At that rate we would have 16 by the end of the year. That is well under the rate of 22 in the last couple of years.

Same goes for mag 6. Currently the average is on the low side. 21 Dec 2012 is going to be a damp squib at this rate

This is the really crappy part of quake watching.

Confirmation from the tensor solutions. This has now been downgraded to a Mag 7.1

USGS

Update : Universidad de Chile Santiago has increased the Magnitude from 6.4 to 6.8. The depth is now reported as 33.4 km. Both values are stronger than initial reports, but are a lot less severe than the data from other seismological agencies.

earthquake-report.com...

They are not taking account on the 6.8 ML being the Richter scale.

I can't see any aftershocks to speak of for this - is that usual? I would have thought there would have been a few by now? Or maybe I'm not looking in the right places

This is a prelude to the 7.6 that will hit SF on Friday 3/30. 2nd line.

reply to post by UnBreakable


Why do you think a 7.6 will hit there on that precise date? You don't think they may have an EQ on the 29th?

Just wondering where you got this info from.

reply to post by Evltre


There will be aftershocks but there are considerably fewer aftershocks in Chile than in some areas such as Japan.

You can expect one at the Mag 6 level fairly soon I guess.

There have been a couple at levels that USGS probably would not report
